Human–Wildlife Interactions
Interactions between humans and wildlife include a number of consumptive and non-consumptive forms. In some cases, the increased demand for wildlife viewing can precipitate new human–wildlife conflicts. Mountain goats (Oreamnos americanus; goats) are native to a number of North American mountain ranges from southeastern Alaska to southwestern Montana, USA. Goat habitat typically consists of steep terrain and cold weather habitats, which has left them particularly vulnerable to climate change. Their alpine environments also make them vulnerable to disturbance by aircraft and land-based motorized human activity. We reviewed and characterized situations in which goats in close proximity to humans …
Tradeoffs May Counteract Effects Of Telecommunication Towers On Osprey Nesting, Gage R. Barnes, Kate G. Slankard, John B. Hewlett, Andrea K. Darracq
Tradeoffs May Counteract Effects Of Telecommunication Towers On Osprey Nesting, Gage R. Barnes, Kate G. Slankard, John B. Hewlett, Andrea K. Darracq
Human–Wildlife Interactions
The number of telecommunication towers (TCTs) throughout the United States has and continues to increase exponentially. Increased TCT placement has been implicated in local population increases in platform nesting birds such as ospreys (Pandion haliaetus). However, osprey use of artificial structures can cause conflicts with humans because of economic costs and risks to human safety. Managers require better information regarding the effect of artificial nesting surfaces, such as TCTS, on osprey reproduction to make informed decisions regarding species conservation and to mitigate potential conflicts. The objective of our study was to evaluate the influence of TCTs on osprey …
Trico: A Novel Repellent For Preventing Deer Damage To Ornamental Shrubs, Paul D. Curtis, Brian C. Eshenaur
Trico: A Novel Repellent For Preventing Deer Damage To Ornamental Shrubs, Paul D. Curtis, Brian C. Eshenaur
Human–Wildlife Interactions
Homeowners whose landscape plants are repeatedly browsed by white-tailed deer (Odocoileus virginianus; deer) desire repellent products that are effective and long-lasting. We conducted a 12-week trial from January 6 through April 5, 2021 to test the duration and efficacy of a novel deer repellent (Trico®) relative to Plantskydd®, a commonly used deer repellent, and untreated plants. We placed treated and control Japanese yew shrubs (Taxus media ‘Hicksii’) at 4 homeowner sites (Birch Hills Drive, Fairview Crescent, Pinegrove Ave., and St. Paul Blvd.) near Rochester, New York, USA, where we detected deer presence. Yews are frequently eaten …

Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper
Human–Wildlife Interactions
Human–carnivore conflicts (HCCs) are increasing globally. These conflicts may encompass competition for food resources, crop and livestock depredations, and attacks on humans. Concerns over conflicts may result in retaliatory killings of carnivores and negative views of wildlife or landscape conservation. Yet, despite the economic and conservation implications of HCCs, data regarding the magnitude and severity of the conflicts may be lacking because many incidents are unreported. To better inform this issue, we compared HCC data for 2016 to 2018 obtained from official records of the Punjab Wildlife and Parks Department for a newly established national park in the Punjab Region …
Stakeholder Acceptance Of Wild Equid Fertility Control Mirrors Global Shifts In Attitudes To Wildlife Management, Giovanna Massei, Stephanie L. Boyles Griffin
Stakeholder Acceptance Of Wild Equid Fertility Control Mirrors Global Shifts In Attitudes To Wildlife Management, Giovanna Massei, Stephanie L. Boyles Griffin
Human–Wildlife Interactions
Wild equid (horses [Equus ferus] and burros [E. asinus]) populations have increased on public lands in the United States since the passage of the Wild Free-Roaming Horses and Burros Act of 1971. As of March 1, 2022, the Bureau of Land Management (BLM) estimated that wild equid populations on designated herd management areas (HMAs) may exceed 82,000 animals. In 2020, the total population of wild equids in the United States was estimated to exceed 300,000 animals. The BLM sets an appropriate management level (AML) for wild horse and burro herds on each HMA and removes animals …
Landscape Characteristics Predict Locations For Potential Human–Wildlife Interactions With Timber Rattlesnakes In Minnesota, Usa, Ben M. Borash, Benjamin P. Pauli
Landscape Characteristics Predict Locations For Potential Human–Wildlife Interactions With Timber Rattlesnakes In Minnesota, Usa, Ben M. Borash, Benjamin P. Pauli
Human–Wildlife Interactions
While management measures cannot eliminate human–wildlife conflicts, they have the potential to minimize the damage done to both parties, especially if areas where the nature of the potential interaction can be predicted before an encounter occurs. The timber rattlesnake (Crotalus horridus) represents a wildlife species associated with public misconceptions that may foster unwarranted fears and retribution. This species is native to the eastern and southern regions of the United States, including a small population remnant in the southeastern region of Minnesota. To gain a better understanding of the environmental predictors relevant to human–snake encounters in Minnesota (that require …
Raven Control From A Conservation Biology Perspective, David J. Delehanty
Raven Control From A Conservation Biology Perspective, David J. Delehanty
Human–Wildlife Interactions
The common raven (Corvus corax; raven) is a large, highly intelligent passerine songbird with a Holarctic distribution attributable to a high degree of plasticity in its foraging and nesting behavior. Historically, ravens have received special attention in human culture, being either respected or vilified. In the western United States, ravens are exploiting the expanding human enterprise, which provides them with unintended subsidies of food, water, and breeding locations, allowing ravens to expand their range and increase in population density and resulting in raven depredation threatening species of conservation concern. From a conservation biology perspective, increased raven populations present …
One Step Closer To A Better Starling Trap, James R. Thiele
One Step Closer To A Better Starling Trap, James R. Thiele
Human–Wildlife Interactions
European starlings (Sturnus vulgaris) are an invasive species in the United States that damage agriculture, personal property, and threaten human health and safety. The U.S. Department of Agriculture Wildlife Services provides technical support to mitigate damage by controlling starling populations at concentrated animal feeding operations, landfills, utilities, and urban areas. Wildlife Services uses DRC-1339, a registered toxicant, to reduce starling populations. Trapping can also be an effective tool but requires more time at a higher cost than DRC-1339. Trapping starlings, however, may be needed to provide a viable alternative to mitigate damage in areas where toxicant use may …

Nd2 As An Additional Genetic Marker To Improve Identification Of Diving Ducks Involved In Bird Strikes, Sarah A. M. Luttrell, Sergei Drovetski, Nor Faridah Dahlan, Damani Eubanks, Carla J. Dove
Human–Wildlife Interactions
Knowing the exact species of birds involved in damaging collisions with aircraft (bird strikes) is paramount to managing and preventing these types of human–wildlife conflicts. While a standard genetic marker, or DNA barcode (mitochondrial DNA gene cytochrome-c oxidase 1, or CO1), can reliably identify most avian species, this marker cannot distinguish among some closely related species. Diving ducks within the genus Aythya are an example of congeneric waterfowl involved in bird strikes where several species pairs cannot be reliably identified with the standard DNA barcode. Here, we describe methods for using an additional genetic marker (mitochondrial DNA gene NADH …
The Emerging Conflict Of Common Ravens Roosting On Electric Power Transmission Line Towers In Montana, Usa, Marco Restani, James S. Lueck
The Emerging Conflict Of Common Ravens Roosting On Electric Power Transmission Line Towers In Montana, Usa, Marco Restani, James S. Lueck
Human–Wildlife Interactions
Bird interactions with electric power lines can cause faults (e.g., disruption of electrical service). Faults on 500kV transmission lines in Montana, USA, which are integral to the Northwest USA power grid, became concerning during winter 2016–2017. In 2017 we found insulators contaminated with bird droppings and discovered a large nocturnal roost of common ravens (Corvus corax). To assess the potential magnitude of the impact of raven roosts on electric power transmission, we summarized fault data obtained from the Energy Management System and raven abundance data obtained from the Christmas Bird Count in central Montana from 2005 to 2020. …

Line Of Sight: Simulated Aerial Avian Predators Can Reduce Problematic Bird Flyovers Of Airfields, William O'Shea, Neil E. Coughlan, Thomas C. Kelly, Neil Mitham, Jeremy Nicholson
Human–Wildlife Interactions
Collisions between birds and aircraft (bird strikes) are a serious threat to air safety and represent a substantial economic cost to the global aviation industry. In recent years, the frequency of wood pigeons (Columba palumbus) flying over active runways has increased at airports in Ireland. Here, we examine the effectiveness of imitation hawk-kites as a means of excluding wood pigeons from sensitive airfield locations. Over 2 years, during August and September, we conducted control (no kites deployed) and treatment trials (kites deployed) at Casement Aerodrome, an active airfield of approximately 320 ha in County Dublin, Ireland and on …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft
Human–Wildlife Interactions
Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma). The 5 wildlife species …

Remote Sensing Applications For Abating Aircraft–Bird Strike Risks In Southeast Brazil, Natalia S. Novoselova, Alexey A. Novoselov, Arthur Macarrão, Guilherme Gallo-Ortiz, Wesley Rodrigues Silva
Human–Wildlife Interactions
The rising number of aircraft collisions with birds requires the development of appropriate mitigation measures to control their populations in the vicinity of airports. The black vulture (Coragyps atratus; vultures) is considered one of the most dangerous species for aviation in Brazil. To better understand the spatial distribution patterns of flying vultures and the risks they may pose to aviation, we studied natural and anthropogenic superficial factors and then numerically estimated and mapped the risk of collision with birds over the Airport Safety Area (ASA) for the Amarais Airport and Presidente Prudente Airport in the southeast part of …
Baboon And Vervet Monkey Crop-Foraging Behaviors On A Commercial South African Farm: Preliminary Implications For Damage Mitigation, Leah J. Findlay, Russell A. Hill
Baboon And Vervet Monkey Crop-Foraging Behaviors On A Commercial South African Farm: Preliminary Implications For Damage Mitigation, Leah J. Findlay, Russell A. Hill
Human–Wildlife Interactions
Conflict between crop farmers and wild nonhuman primates is a worldwide conservation issue of increasing concern. Most of the research on wild primate crop foraging has so far focused on the conflicts with subsistence agriculture. Crop damage caused by primate foraging in large-scale commercial agriculture is also a major facet of human–wildlife conflict. Despite its increasing severity, there are very few published accounts of on-farm wild primate crop-foraging behavior or effective techniques to deter primates from field crops on commercial farms. To address this knowledge gap and identify some mitigation strategies, we used direct observation from a hide to collect …
Field Guarding As A Crop Protection Method: Preliminary Implications For Improving Field Guarding, Leah J. Findlay, Russell A. Hill
Field Guarding As A Crop Protection Method: Preliminary Implications For Improving Field Guarding, Leah J. Findlay, Russell A. Hill
Human–Wildlife Interactions
Negative interactions between crop farmers and wild primates are an issue of significant concern. Despite many crop farmers using field guards as a method of crop protection against foraging primates, there are very few published accounts of how effective this technique is and how it might be improved. To bridge this knowledge gap, we used direct observations from a hide to collect the behaviors of field guards, chacma baboons (Papio ursinus; baboons), and vervet monkeys (Chlorocebus pygerythrus; vervets) foraging in a 1-ha butternut squash (Cucurbita moschata) field for 4 months (May to August) in …

After Decades Of Suburban Deer Research And Management In The Eastern United States: Where Do We Go From Here?, Paul D. Curtis
Human–Wildlife Interactions
State wildlife agencies have regulatory authority and oversight over deer (Cervidae) management in the United States. However, increased urban sprawl and overabundant deer populations have created increased human–deer conflicts. Because of the growing controversy surrounding the use of traditional management practices such as regulated hunting in suburban areas in the eastern United States, managers are now using specialized tools and management approaches to reduce deer conflicts in urban areas. However, this has created new challenges as they try to meet the desires of diverse stakeholder groups. Although deer management programs in urban areas differ somewhat in every state, effective management …
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Human–Wildlife Interactions
Crow (Corvus spp.) populations are increasing globally. This is cause for concern because overabundant crow populations can damage agricultural crops, harm native wildlife, and become a nuisance in urban areas. In Japan, the carrion (C. corone) and large-billed crow (C. macrorhynchos) can cause damage to crops and livestock. This damage is predicted to increase in Japan with climate change, especially when precipitation increases, inducing landscape changes that may favor crow populations and activities. In Japan, the primary control method used to manage crow damage is the destruction of nests by a crow control officer who …

Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales
Human–Wildlife Interactions
Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions of wildlife …

Tracking Canada Geese Near Airports: Using Spatial Data To Better Inform Management, Ryan J. Askren, Brett E. Dorak, Heath M. Hagy, Michael W. Eiccholz, Brian E. Washburn, Michael P. Ward
Human–Wildlife Interactions
The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the …

Train–Elephant Collisions In A Biodiversity-Rich Landscape: A Case Study From Rajaji National Park, North India, Ritesh Joshi, Kanchan Puri
Human–Wildlife Interactions
Linear developments like railways and highways have a negative impact on ecological processes of wildlife species at a landscape level. The impacts in terms of wildlife mortality and threat to surviving populations of species have been well-studied; however, less work has been done to understand the potential causes of train–wildlife collisions, particularly large mega-fauna such as Asian elephants (Elephas maximus; elephant). In this case study, we review train–elephant collisions (TECs) that occurred in Rajaji National Park (RNP) and discuss some potential causes of TECs along with mitigation measures. The RNP, located in the upper Gangetic plains of northern …

Sloth Bear Attacks On Humans In Central India: Implications For Species Conservation, Nisha Singh, Swapnil Sonone, Nishith Dharaiya
Human–Wildlife Interactions
Conflicts with wild animals are increasing as human populations grow and related anthropogenic activities encroach into wildlife habitats. A good example of this situation is the increase in conflicts between humans and sloth bears (Melursus ursinus) in India. Sloth bears are known for their aggressive and unpredictable behavior. More human fatalities and injuries have been attributed to sloth bear attacks than all recorded incidences of wildlife attacks in Buldhana Forest Division of Maharashtra, India. We interviewed 51 victims that were attacked by sloth bears between 2009-2017 to better understand the reasons for the attacks. Thirty-four of the attacks …
Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale
Wind Energy Development: Methods For Assessing Risks To Birds And Bats Pre-Construction, Todd Katzner, Victoria Bennett, Tricia Miller, Adam Duerr, Melissa Braham, Amanda Hale
Human–Wildlife Interactions
Wind power generation is rapidly expanding. Although wind power is a low-carbon source of energy, it can impact negatively birds and bats, either directly through fatality or indirectly by displacement or habitat loss. Pre-construction risk assessment at wind facilities within the United States is usually required only on public lands. When conducted, it generally involves a 3-tier process, with each step leading to more detailed and rigorous surveys. Preliminary site assessment (U.S. Fish and Wildlife Service, Tier 1) is usually conducted remotely and involves evaluation of existing databases and published materials. If potentially at-risk wildlife are present and the developer …

Avian Fatalities At Wind Energy Facilities In North America: A Comparison Of Recent Approaches, Douglas H. Johnson, Scott R. Loss, K. Shawn Smallwood, Wallace P. Erickson
Human–Wildlife Interactions
Three recent publications have estimated the number of birds killed each year by wind energy facilities at 2012 build-out levels in the United States. The 3 publications differ in scope, methodology, and resulting estimates. We compare and contrast characteristics of the approaches used in the publications. In addition, we describe decisions made in obtaining the estimates that were produced. Despite variation in the 3 approaches, resulting estimates were reasonably similar; about a quarter- to a half-million birds are killed per year by colliding with wind turbines.
Impact Of Wind Energy On Bats: A Summary Of Our Current Knowledge, Cris D. Hein, Michael R. Schirmacher
Impact Of Wind Energy On Bats: A Summary Of Our Current Knowledge, Cris D. Hein, Michael R. Schirmacher
Human–Wildlife Interactions
Since 2003, when it was discovered that large numbers of bats were being killed at wind turbines in the eastern United States, our understanding of the impact of wind energy development on bats has increased and consistent patterns of fatality, including seasonality and species composition have become evident. Yet, many questions remain despite the wealth of data collected across numerous post-construction monitoring studies. We synthesized the recent literature to provide an overview of our current understanding of patterns of bat fatalities at wind energy facilities in the United States and Canada. Our understanding of the impact of wind energy development …
Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband
Parallel Universes? Increasing Connections Between Ipm And Wdm, Lynn Braband
Human–Wildlife Interactions
Managing damage by wild vertebrates often is important, and wildlife damage management (WDM) has incorporated important tenets of integrated pest management (IPM). However, largely separate academic backgrounds have nurtured the IPM and WDM communities. The controversial “hot button” topics have tended to differ. While WDM research and outreach have received some IPM funding, and wildlife studies occasionally appear in IPM journals, attendance at infrequent wildlife sessions during IPM meetings has been sparse. The objectives of this paper are to review important examples of collaboration, and evaluate possibilities for future synergy between these related disciplines.

The National Wildlife Control Training Program: An Evolution In Wildlife Damage Management Education For Industry Professionals, Paul D. Curtis, Raj Smith, Scott Hygnstrom
Human–Wildlife Interactions
Managing wildlife and reducing damage in rural areas has traditionally been achieved by hunting and trapping problem species or by preventing animals from accessing crops and entering buildings. With urban sprawl, specialized tools and management approaches often are needed to reduce wildlife conflicts in developed landscapes. To address these issues, the private wildlife control industry has grown considerably during the past 2 decades. State wildlife agencies have regulatory authority and oversight of this industry, and there is an increasing trend toward licensing or certification of commercial wildlife control operators (WCOs). Regulations differ in every state, however, and no consistent standard …

Modeling The Economic Impacts Of Double-Crested Cormorant Damage To A Recreational Fishery, Stephanie A. Shwiff, Katy N. Kirkpatrick, Travis L. Devault, Steven S. Shwiff
Human–Wildlife Interactions
The double-crested cormorant (Phalacrocorax auritus) has undergone a significant range expansion in the Great Lakes area of the United States since the 1970s, negatively impacting native fish populations and sport fisheries. Effective management of wildlife requires policies and practices that quantify their economic impacts, which is often complicated by multiplier effects in the regional economy. This analysis estimates the potential direct and regional economic impacts of the cormorant to a recreational fishery. We estimated that the potential economic loss was on average $5 million to $66 million annually, as well as 66 to 929 job-years in the region …

Assessing Gull Abundance And Food Availability In Urban Parking Lots, Dan Clark, Jillian J. Whitney, Kenneth G. Mackenzie, Kiana K. G. Koenen, Stephen Destefano
Human–Wildlife Interactions
Feeding birds is a common activity throughout the world; yet, little is known about the extent of feeding gulls in urban areas. We monitored 8 parking lots in central Massachusetts, USA, during the fall and winter of 2011 to 2013 in 4 monitoring sessions to document the number of gulls present, the frequency of human–gull feeding interactions, and the effectiveness of signage and direct interaction in reducing human-provisioned food. Parking lots were divided between “education” and “no-education” lots. In education lots, we erected signs about problems caused when people feed birds and also asked people to stop feeding birds. We …

Evaluating Competing Preferences Of Hunters And Landowners For Management Of Deer Populations, Gino J. D'Angelo, Marrett D. Grund
Human–Wildlife Interactions
Most state wildlife agencies consider public input in the management of whitetailed deer (Odocoileus virginianus) populations. In 2013, we surveyed deer hunters (n = 3,600) and landowners (n = 4,604) in southwest Minnesota to gauge their preferences for managing deer. We hypothesized a priori that, irrespective of their perceived impacts of deer, hunters would prefer deer populations to be increased and landowners would prefer deer populations to be decreased. Our findings suggest that defining stakeholder groups according to primary associations with deer (i.e., farming and hunting) accurately categorized differences in tolerance levels for deer populations in …

Administering GonaconTm To White-Tailed Deer Via Hand-Injection Versus Syringe-Dart, Charles S. Evans, Anthony J. Denicola, John D. Eisemann, Robert J. Warren
Human–Wildlife Interactions
Immunocontraceptive vaccines have shown some promise for fertility control of white-tailed deer (Odocoileus virginianus) in urban and suburban habitats where traditional methods of population control may not be applicable. Currently, the only contraceptive vaccine approved by the U.S. Environmental Protection Agency for use in white-tailed deer is GonaConTM Immunocontraceptive Vaccine, but it is registered for use via hand-injection only. It has been suggested that remote-delivery of immunocontraceptives would be more cost-effective than hand-injection, but there is the potential for incomplete injection from a syringe-dart. Therefore, the purpose of our research was to: (1) conduct a dart configuration …
